mouseover/mouseout are fired if the mouse is moved either over a child of
the target or another node in the document tree, so you need to check if
the element to where the mouse is going is a descendant of the previous
node. Like, onmouseover, check that target is a descendant of
relatedTarget.
Then, since :hover styles are applied dynamically, without any script
intervention, you can read the computed styles for some element in the
DOM, using getComputedStyle(...)
